LAMP.

Be it known that I, Gnonen W. Gmnnfrrn, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and -useful 'Improvements' in Lamps, of which the following is-.a specification.

This invention relates generally to lamps, and particularly to that class of such devices which are utilized `for search-lights and extensive illuminatiotn. l

More specifically the invention relates .to a casing provided with a reflector and a the holder being adjustable on the axis of the reflector for obtaining the. focus, and also adjustable vabove and below the axis for the deflection of the light either upward orvdownward.

' Hector casing The invention may be further briefly summarized as consisting in the construction' and combinationof parts hereinafter set forth gin` the following. description, drawings and claims.

Referrin tothe drawings, Figure 1 -isa view` in s e elevation and section showing the device; and Fig. 2 is a viewf of a lower portion .in front elevation showing the means for` adjusting.

In carrying out the invention anyltype of casing and reflector-may be utilized so long as theypossess the necessary characteristics, in the drawings, andA in this arrangement 1 represents a suitable framework which supports a inni-neasing 2 provided with a re- 3.A This casing 3 is provided i with theA usual door 4 receiving the usual 'glass front 5. Within the reflector' casing 3 is a reflector G, 'and this reflector is provided with a suitable bolt 7 andnut 8 at the .center for holding it i-n place within the reflector casing. The reflector 6 is cut away or slotted. at l9 for receiving the lamp,

will appear, and this opening alines .with a similar opening 10 in the reflector casing 3.

Mounted upon the underside'of the casing 2' .is a slide 1l adapted to move from front to reni', in suitable guides 12 secured to the underside of the main A'casing 2. This slide 11 is provided-with a downwardly extending lug 13 which receives a threaded shank .le of an adjusting screw 15 held against Speoication of Letters Patent.

' able vertically in sai -through a slot in th lower portion of said but'I have shown one embodiment Patented Jan. so, 1917.

movement of the slide by a bracket lise- I cured to the back of-the casing 2, a suitable nut 17 beingv arranged on the inside of the bracket to prevent the backward movement of the screw. The slide is :provided with a' boss 18 adapted to reeive atubularsupport 1 9 carrying a lamp socket 20 at its upper end for Vthe reception of a nitrogen lamp 21. The support .1,9 is-preferably made hollow and receives the wires 22 and is slidable in be seen that the lamp may be moved in and out lon the aitisof the reflector foi-'obtaining the proper focus and may be raised or lowered within the reflector so as to reflect the light either upward or downward.

Having described my invention, I claim :#1

1. In a lamp, a stationary frame, a reflector rigidly mounted.V thereon, horizontal guide-ways on said frame tor and parallel with its axis, a slide mov- .able 'in said guide-ways, slide adjusting meansA anda lamp su porting tube adjusti dpslide and 'extending below said relec-.

2. In a lamp, a stationary 4fram-e, a refle- A tor rigidly mounted' thereon and havmg a.

,longitudinal bottoml slot', a casing inclosmg the rear portion of the re.-

having a longitudinal guide-ways extending and protecting flectorfsaid ,casing slot in its bottom,

longitudinally of said casing slot outside' of.

.'n'id casing and attached thereto, ya slide movable 1n said guide-way, means outside of snidcasing for adjusting said slide, and

a lump. holding tubeextending through said lslide' and said slots from the outside of said casingrtothe inside otsaid reflector and adj ust-able in said slide, and lmeans on the outside. of said Acasing for holding said tube 1n adj usted position.
